Dear ANSYS support team

I am going to perform the viscoelasticity harmonic for a ruber like material at room temperature. Material supplier told me they only can do the compression DMA test for such frequency dependent properties, I am worried about the simulation accuracy with properties obtained with a comprssion test. Is there a requirement for such material properties testing? Is there a test standard? Thank you!
